The need: process transparency and efficiency
Piraeus Bank, a prominent Greek multinational financial services company with €34.7 billion in net loans and 5.7 million customers, faced challenges in clarifying its consumer loan process.
With a substantial monthly workload of 20,000 applications and 110,000 user events, the process was complex and often handled non-standardly. Traditional approaches like process mapping, interviews, and workshops failed to depict the true reality of the process, and automation proved ineffective.
Business needs:
- Creating a detailed end-to-end process visualisation of the consumer loan process
- Identifying the key bottlenecks in the selected process
- Monitoring KPIs and rework in the process flow
- Identifying deviations from the designed process
- Identifying root causes for inefficiencies
- Identifying areas of improvement to optimise performance

Locating process bottlenecks and increasing efficiency
Through process mining, Piraeus Bank revealed bottlenecks, inefficient process variants, and their origins. They conducted root cause analyses for various inefficiencies, pinpointing optimisation opportunities. Additionally, the insights gained shed light on why automation initiatives deviated from plans and suggested necessary changes for problem resolution.
Piraeus Bank got much more than transparency. They:
- uncovered bottlenecks
- found inefficiencies and their root causes
- pinpointed optimisation points
- got indispensable automation insights

The result: “Unprecedented transparency”
Using the fact-based insights from process mining, Piraeus Bank made effective improvements and optimised the process, resulting in an impressive 86% reduction in process lead time.
“Thanks to QPR, we were able to demonstrate process bottlenecks to the broader management, identify optimization points and make recommendations to improve the consumer loan process.”
